Thanks for the quick replies everyone. The diesel option is definitely more expensive, but can I expect to receive a greater return from that as opposed to just rebuilding/replacing the patro Atomic 4?

If I buy a used/rebuilt Atomic 4 online and have the yard install it the costs will be similar to just rebuilding the Atomic 4 I currently have...

Thoughts?

A fiend of mine T37Chef just replaced his engine, similar size with a beta. His total costs were greater than $9000 and he did a fair amount of the work himself
